Frequently asked questions
Is the Blaze King Industries Princess PI29 Insert EPA certified?
The Blaze King Industries Princess PI29 Insert holds EPA certification number 123-18a but is no longer on the current certified list — it is previously certified, which usually means the model is out of production. Already-installed units are unaffected by that status in most jurisdictions.
What is the Blaze King Industries Princess PI29 Insert's emission rate?
The Blaze King Industries Princess PI29 Insert is certified at 1.3 grams of particulates per hour (tested with crib wood). Real-world emissions depend heavily on fuel moisture and operation — the lab figure assumes seasoned fuel and correct air settings.
How many square feet can the Blaze King Industries Princess PI29 Insert heat?
Roughly 700–950 sq ft, estimated from its 24,348 BTU/h peak output at 25–35 BTU/h per square foot. Insulation, climate, ceiling height, and floor plan move this figure substantially in both directions.
Does the Blaze King Industries Princess PI29 Insert qualify for a federal tax credit?
No — the federal 25C credit for biomass stoves was terminated for property placed in service after December 31, 2025. The Blaze King Industries Princess PI29 Insert's certified efficiency is 75% HHV, which met the credit's ≥75% HHV threshold while it existed. State and local incentive programs may still apply — check your state energy office and air district.
